HAY-SHOCKER.

Maaate.

' To'aZZ whom it may concern e Be it known that we, HENRY E. GREGORY andCHARLES A. GREGORY, citizens of the United States, andresidents ofTrinidad,

in the county of4 Las Animas and State of 'C olorado,have invented a newland `Im= f proved!HayfShocke'r, of which the follwn wheels 18.

' ing is a full', clear', and exact description.

' Our invention relates to a hay shocking apparatus to be associatedwith a hay rake, and following the latter, so that as the hay is rakedand dumped in a windrow, the.y

shocking apparatus will pick up the dumped v, ,hayfand/"deposit" thesame ina receptacle.

When suthcient hay has been accumulated in theI receptacle to form ashock the shock is ing drawings forming a part of this speciication, inwhich similar characters of reference indicate corresponding parts inall the views.

15". The rear end of the shocker case'isv open. A drop bottom isprovided for the shockercase, preferably consisting of a grid,presenting rearwardly extending tines 16 and a head'17, which isrockably mounted at its `ends in the sides of the shocker case 15. Theshocker has any suitable vsupporting T he shocker includes apick'fup'fork following the dumping rake 13, the said fork havlng a heador cross bar 19 from which extend forwardly projecting pick-up fingers`or tines 20. In the rear of the tines 20, per-l 26 secured to thelongitudinal frame barsy 14 of the shocker. The wheels 18 of the shockerare preferably secured tothe said cross bar 26.

Thev fork is so constructed that the pickup fingers 20 and the head orcross bar 19 carrying the same, may have pivotal movement relatively tothe perpendicular tines or rack 21. The pivotal connection may beestablished by pivots 27, near each end, which pass through hinge lugs28 on the cross bar 19 and a hinge lug 29 on the carrying arms 23 of theorl The fork-operating means are actuated from devices advantageouslyarranged on the rake so as to be controlled by the driver, and haveoperative connection with the rock shaft 24 to swing the fork verticallyto dump the picked-up windrow into the shocker case 15.

Referring particularly to Figs. 1 and 2, it will be' seen that the rockshaft 24 is formed with crank arms 30, the'upper ends .r 31 of which arereturn-bent rearwardly.

extend from the crank arms of the rock shaft rearwardly. around idler`sprockets 33 onthe sides of the rocker case 15, and said chains'feXtend forwardly and preferably around guidev sheaves 34,.fto aiconnection with operating drums 35' on the rake.

The drums 35 are loose on the axle 12 of the rake, and means is providedunder the control of the driver to throw the drums into and out of gearwith the wheels 11,. so that :the drums may be given a partial turn todump the fork. We have illustrated one means for making and breaking theoperative connection between the chain-actuating drums and the wheels11. As the drums and their appurtenances are the same at each side ofthe rake, it will suiiice to describe the devices at one side. 0n eachwheel 11 is secured a ratchet wheel 36 to rotate with the wheel 11, theannular series of ratchet teeth being indicated by the numeral 36a. Apawl 37 adapted t'o engage with the ratchet teeth 36@ is carried by aloose drum 35, said pawl being mounted on a rockable pin or shaft 38. A.retractile spring 39 is secured t0 the pawl 37 and to a pin 40 in thedrum 35. Said spring normally tends to maintain the pawl out ofengagement with'the ratchet teeth 36a. Fixed` on the shaft or pin 38 onthe outside of the drum 35, is an arm 41, and means is provided underthe control of the driver to engage the'said arm 41 and so rock itsshaft 38 as to throw the pawl '37 into engagement with the ratchet wheel36.

With the illustrated meansfor controlling the arm 41, the normalposition of the arm 41 when the fork is in the lowered po- Sition, isadjacent to a rocker arm 42 on a shaft 43, rockable in suitable bearingson the frame 10 of the rake, and the said shaft is adapted to be rockedby the driver from his seat 44 on the rake. The operative connectionswith the shaft 43 may consist of a pedal 45 on a shaft 46 carrying anarm 47 connected by a'link 48 with a similar arm 49 on the rock shaft43. Thus the driver by pressing down on the pedal 45 will rock the arm42 inwardly into Contact with the arm 41 on the shaft 38, and thus rockthepawl `37 into position to be engaged by a tooth 36*l on the" ratchetwheel 36 and thereby cause the drum 35 to be turned for* wardly. Thenormal position of the arm 41 is illustrated in Fig. 1, and in dottedlines in Fig. 3. The position of the arm 41, in

' full lines Figs.4 3 to 5, is an intermediate one when said arm isbeing carried by the turning of the drum from the original positionadjacent to the arm 42. The continued movement of the drum 35 and thearm 41 and pawl 37, will cause the said arm 41 to be engaged by atripper device to automatically throw thepawl out of engagement with theratchet wheel 36. The said tripper device may consist of a bracket 50having an inclined surface so that the engagement of the arm 41 withsaid inv clined surface will rock the said arm upwardly and thus rockthe pawl 37 out of engagement, and thereby disconnect the drum 35. Whilethe pawl is engaged, the drum 35 will be turned through such an angleand will be of such a diameter as to wind in the proper length of thechain 32 to give the lifting movement to the fork'by a pull of thechains on the arms 30, 31, of the shaft 24.

Itis required only that the fork be swung to a position beyond avertical line passing through the shaft 24 so that the 4preponderance ofweight of the fork will be rearward of the said vertical line. Themomentum of the fork will cause it to bring up against a stop providedat the forward end of the shocker case 15. Preferably the stop takes.

, shocker. The preponderance of the weight of the fork will tend tomaintain the fork in the raised position against the stop 51. Thepivotal connection of the tines 20 and head 19 with the lifting arms 23permits the said tines to rock relatively to the tines 21, so that whenthe arms 23 and the ,tines 21 are arrested, a relative movement of thetines 20, as well as the momentum .of the hay, will cause the latter tobe dumped from the fork into the shocker case 15.

It is to be noted that as the fork approaches the dumping position itwill be released ;from operative control by the drum 35, owing to theautomatic disengagement of the pawl'37 and the ratchet wheel .36. Inorder to cause the fork to return to the lowered position we provideretractile springs 56, connected at one end, as at 57 to the side bars14 and connected at the opposite end with the cross bar 22, orequivalent rigid member of the fork. The arrangement is such that thesaid springs 56 will be placed under tension by the final movement ofthe fork, when momentum has carried it to a position against the stop51, and therefore the said fork having dumped and having been releasedby the disengagement of the drum 35, will be drawn backwardly by thereaction of the springs 56 a sufficient distance to bring thepreponderance of weight forward of the pivotal center, so that the forkwill then gravitate to the lowered position. f

7e provide means whereby when the fork drops to the lowered position,the pick-up tines 20 will be positioned sufficiently close to the groundto effectively pick up the hay, and will be prevented from dropping to aposition to dig into the ground. For the desired purpose the head orcross bar 19 carrying the pick-up tines 20 is provided with a rearwardlyextending arm 53 y(Figs. 1 and 2), to the upper end of which isconnected one end of a short chain 54, the opposite end of said chainbeing connected to an eye 55a on the upper end of an arm 55, said armbeing rigidly secured at its lower end to the cross bar 26, so that thesaid chain will limit the downward movement of the arm 53 and causeV amovement of the head 19 and its pick-up fingers 20 on the pivots 27thereby disposing the pick-up tines at the proper downward inclination.The movement of the head 19 on the pivots 27 may, if desired, belimited, as shown best in F ig. 1, bythe feet 23a on the lower ends ofthe fork-carrying arms 23.

y It will be observed that the retaining tines 21 are rigid with thefork-carrying arms 23, while the pivotal movement of the pick-up tines2O is relative to the said carrying arms and relative to the saidretaining tines; also the retaining tines are shorter. The result isthat when the fork is in the dumping position, the said pick-up tines 20will extend over the shockercase-lo and beyond the retaining tines 21,and the said pick-up tines will be permitted a downward dropindependently of the carrying arms 23 and the retaining tines 21.

When suiiicient hay has been deposited in the receptacle 15 to form ashock, the said shock is dumped by the driver, this being accomplishedby the hand lever 59 connected by a link 60 with an upwardly extendingrocker arm 61 on the rock bar 17 of the grid 16 constituting the bottomof the shocker case 15.

It will thus be seen that the driver manually controls the dumping ofthe rake, and then manually controls the operating means for lifting thefork, following which the fork is automatically released from itsoperating means, and is automatically returned to the lowered position;the driver then having'manual control of the grid and the shocker casefor dumping the accumulated shock.
